Dynamic systems offers high-performance linear ball bearings. The efficient design allows only minimum friction between precision bearing balls and shafts providing smooth movement with high accuracy. Outer sleeve is made of high carbon chromium bearing steel. Hardened and ground sleeve provides secure fit between the bearing linear race and the bearing housing. Balls are guided by the retainer throughout the circulating cycle. The smoothness of ball guiding surface guarantees low noise operation even at high travel speed. Lm series linear bushings are widely used in general industrial machines, packaging machines, automation, measuring equipment, x-y slides, etc.
